What Is The Average Cost Of A Home Solar System

The Quality Of The Solar Panels Used

Not all solar panels are the same!

See our guide to the different types of solar panels for more details, but in a nutshell there are three types:

• Monocrystalline solar cells are the most efficient at 15-22%, but they are also the most expensive type of solar cell.
• Polycrystalline cells are cheaper than monocrystalline, but their efficiency is far lower at just 13-17%.
• The cheapest solar cells of all are amorphous solar cells, which also have the bonus of being more efficient in low-light but they are the least efficient overall at 9%.

How are the efficiency figures calculated? Well it is determined by how many watts of power are produced in a square meter. 100% efficiency means that a square meter of panel would create 1,000 watts. Therefore a panel rated at 18% would create 180 watts from every m2 it follows that panels with higher efficiency ratings create more electricity and this is reflected in the price.

Installation Step By Step

The panels will already have been assembled by the manufacturer in their factory. So, all thats needed onsite, is for the installer to:

Solar Panel Costs By Electricity Generation

The more electricity the system can generate, the greater the savings on your electricity bill can be but the bigger the initial cost.

Its important that your system is sized correctly for your households electricity use, so that you dont overpay.

If you’re not sure what size solar panel system is appropriate for your home, weve also listed prices you should expect to pay based on your annual electricity usage. You can find this on your annual energy statement or in your online account.

But keep in mind that solar panels generate most of their electricity during the day, so you may not be around to use it . In fact, our survey of solar panel owners* found that:

• 12% use less than a quarter of their solar electricity
• 34% use between a quarter and half
• 22% use between half and three quarters
• 13% use more than three quarters.

So you’ll still need to buy electricity from the grid, especially on dark winter evenings.

Battery storage lets you bank electricity generated by your solar panels until you need it, but buying a battery will mean it takes longer for your system to pay for itself. Find out more about solar panels and battery storage. The cost of a battery is not included in the prices above.

Is It Worth It To Install Solar Panels

Many people question if solar panels are worth the investment. The costs of solar panels can be high, to begin with, but the money you save in the long run can justify the high upfront cost. On top of that, with solar panels, you can increase the overall market value of your property.

Additionally, by signing up for funding schemes like the SEG, you can even earn money for the extra energy your panels produce.

Therefore, although the installation cost may seem a little steep, the savings from your reduced electricity bills, as well as, the reduced carbon footprint of your household energy, make the investment worthwhile.

Solar Panel Installation Costs

If you intend taking advantage of the financial help or want to sell the electricity to the National Grid, you must use equipment from an MCS certified manufacturer and use an MCS installer. This ensures that everything is specified, manufactured, installed and maintained correctly. You can check that the companies you deal with are MCS registered by using this search tool on the MCS website.

As always, installation charges will vary depending on where you live in the country. Having said that, the average MCS certified solar panel installer charges between £150 and £200 per day. Unless you are very unlucky and need major alterations to your roof, most jobs wont take longer than about 3 to 4 days. This duration might also vary if you have difficulties accessing the roof.

All installation companies will need scaffolding to provide a safe working platform. Once thats in place its usually very simple for a professional to install the panels.By the way, make sure you are clear about who is organising the scaffolding, and whether the cost is included in your quote.

The type of roof you have is an important factor that will alter the installation cost. For example, An installation on a flat roof will cost less because its easier to access than a pitched roof. Another factor is if you have a very high roof. Very high roofs are more difficult to work on and more dangerous. So, youll find that installers charge at the top end of the day rate range.

Wouldnt you like to generate free electricity for use in your home, or to export to the UK National Grid? It seems like a dream come true, doesnt it? Well, this is something you can do quite easily, with a little help from some photovoltaic solar cells. But, how much do solar panels cost? And, how large must the solar panel system be?

On average, solar panels cost between £1800 and £6100 in the UK. The most common size for domestic solar panels is a 4kWp system.

Most solar PV panels produce around 250Wp. Therefore, to produce 1kWp, youll need 4 panels. So, for 4kWp youll need 16 panels arranged into an array.

. This is the amount of energy generated at peak performance during the summer).

But, why are PV panels popular?Lets start by stating the obvious. Solar energy is clean, and once the receptor array is set up, it needs very little maintenance. Probably, the most important maintenance is to keep the panel surfaces clean. Otherwise, your power output will substantiallydecrease.

Next, another obvious advantage is that your energy bills will decrease. And thirdly, if you produce more than you use, youll see an extra income trickling in from sales to the electricity suppliers.

Building Regulation For Solar Panels

Solar panels are favourably looked upon by the UK government and are catered for under permitted developments. That said, it is necessary to ensure that they are not fitted above the highest point of the property. Also, it is stipulated that the panels shouldnt protrude more than 200mm from the surface of the roof.

Solar panels are also subject to standard building regulations, including your roofs ability to handle the panels and other health and safety measures. On a few occasions, you might even have to prove to the local planning office that your property is suitable for solar panels.

Uk Regulation & Planning Permission

Generally, installing solar panels on your land comes under the category of permitted development. So there should be no need to apply for Planning Permission. However, you must comply with many important conditions to be put in this category. And, these are listed on these Planning Portal pages.

Installation of solar panels comes under the scope of the UK Building Regulations. Generally,

• The existing roof must be able to support the additional load.
• The electrical installation must comply with the current electrical regulations.
• Use a competent installer. You can find one by using the search tool on the UK Government website.
• Alternatively, a competent installer will be certified with the MCS.

Solar Battery System Cost

The batteries make it possible for a home to go off-grid. They collect excess energy and store it for later. This stored energy powers your home at night and when the suns energy is insufficient. Batteries cost between $4,000 – $14,000 for each installation. Several battery types can be used as a backup system with on-grid setups, but going off-grid can currently only be reliably achieved with flooded lead-acid batteries and lithium-ion batteries.

Lead Acid Solar Battery

Lead-acid was once the only type of battery for solar power. They came in two types – sealed and flooded. Sealed is a safer and lower maintenance type of battery, but it has less depth of charge and cannot work for full-time use. Flooded batteries are more maintenance, and they do not last as long, so you need to replace them more often. However, they are less expensive than lithium-ion batteries, lowering upfront costs. They cost between $4,000 and $6,000 on average.

Lithium-Ion Solar Battery

Lithium-ion batteries are the most recommended battery for off-grid systems. They are safer than FLA batteries and do not require maintenance. It lasts much longer, so you do not have to replace them two or more times like an FLA battery. Lithium-ion batteries are smaller and take less space. However, they cost much more, between $12,000 and $14,000. You only need 2 of these batteries versus 8 of the others.

Solar Pv Installation Cost Breakdown

Heres a breakdown for an average 4kWp system with a straightforward install. As well see, these elements can vary depending on many factors, but as a rough guide:

This gives a total system cost of £5,596 ex VAT:

• kit cost £2,511 ex VAT,
• services cost £3,085 ex VAT.

This system was quoted using 13 x JA Solar 310W panels, a Solis 4kW inverter and K2 mounting system on a concrete-tiled, single-orientation, rectangular roof layout.

Condition Of The Roof

The roof is crucial when it comes to the installation of solar panels. Therefore, if it is in poor condition, itll have to be repaired, which costs extra money. Also, if the roof is dirty and needs a wash, it would be more challenging to fix the solar panels, meaning youll also need to pay for cleaning.

Cost Of 5kw Solar System Installed

5kW systems can meet the needs of smaller homes with average energy use in a moderately sunny climate. They can reduce grid dependency in larger homes or work with a backup system for larger homes going off-grid. A 5kW solar system includes an array of panels, inverters, batteries, and controllers. This is a whole-house system, so it requires space inside and outside. These systems typically cost $40,000 to $45,000, with installation usually included for an additional $4,000.

You Shouldn’t Need Planning Permission

You don’t generally need planning permission for solar PV systems. The big exceptions are if your property has a flat roof, is listed or in a conservation area. You might need to get approval from your council’s building control team, so check with your local authority.

In England and Wales, the Government’s Planning Portal says that panels are likely to be considered as “permitted development”.

How Much Does A Typical Residential Solar Electric System Cost

A number of factors determine the final price of a PV system, including its size, component options and configuration, labor costs, local permitting costs and available incentives and tax credits.

The cost of a solar electric system is measured in dollars per watt. The average cost for a residential system is currently $3-5 per watt. That means the average 5-kW residential system will cost $15,000-$25,000, prior to tax credits or incentives.
